on the baja it just started about a month ago (~40k) and never happened before that. It sounds a lot like what you are saying janikphoto. On my 90 Legacy the exact same noise and vibration in the petles was the half axels. And that is what the dealer thought it was as well and after replacing the half axel, it wasn't it. They checked the wheel berrings (all 4), and a lot of other tests on the system and they keep turning back to the trany. I have been having some other issues that I have been working with them as well on that, so that seems logical. I have been having problems with the trany over heating a lot. I have the auto/stick version.
